Density-field structures in a few systems undergoing velocity ordering
Subir K. Das, Sohini Chatterjee, Wasim Akram +3
We consider two (off-lattice) varieties of out-of-equilibrium systems, viz., granular and active matter systems, that, in addition to displaying velocity ordering, exhibit fascinat…
